Product Line Breadth: Why it is Important
You surely already know that assortment breadth is the total number of product categories or types of goods on the sales floor. The more of them there are, the wider the assortment. This is best demonstrated by supermarkets offering food, household chemicals, and clothing at the same time.
Carrying an expansive breadth of assortment has its advantages:
- It attracts customers from different segments. People looking for budget products and those who like premium products will find the right products in the sales area.
- Expands market share. Allows retailers to work several niches simultaneously.
- Increases the average check: including through cross-selling and impulse purchases.
Ultimately, product assortment means a wider customer base and greater brand loyalty, but there are some downsides. A large assortment requires high operating costs for the purchase and storage of goods.
It is also quite difficult to control the turnover of goods and reduce stock. Marketing campaigns are another challenge. You need to constantly determine which product category should be involved in the campaigns and what efforts should be directed to its promotion.
Assortment Depth: When it Matters
Product depth is the variation of the same product within the same category. It can mean different sizes, colors, flavors (if it is food). The more variations there are, the deeper the assortment is, which means that you can:
- take into account all customer preferences and strengthen customer loyalty;
- set yourself apart from competitors with your product assortment (if they offer only basic options).
However, there are also challenges, and the most important one is the cannibalization of sales. The more similar products you have, the greater the risk of a drop in sales of individual items. Product assortment planning and inventory management also become more complicated as you need to carefully control the rotation to avoid stagnation or spoilage.
Product Breadth vs Depth: Typical Inventory Management Strategies
In the end, both product breadth and depth matter. However, not every retailer can offer the widest possible assortment with the greatest possible depth. Striking the right balance is key and there are several established practices to achieve it.
Wider Assortment, Less Depth
This strategy provides coverage of more categories, but with a limited variety of products in each category. As a result, you can attract more customers and cover their basic needs. Risks are reduced by diversifying product groups.
However, customers who were looking for more options within one category will remain dissatisfied. So there is a risk that part of the audience interested in specialized or premium products will be lost.
Best for: supermarkets and hypermarkets, discounters.
Limited Width, Greater Depth
This is how you can create a specialized store that offers a large selection of goods within one or more specific niches and potentially increase customer loyalty while ensuring a high percentage of repeat purchases. An additional advantage is the positioning of the brand as an expert in its segment.
However, this approach severely limits the audience: you will only work with an isolated segment of customers. Customers will be lost if demand for the main product category wanes.
Best for: niche, specialty retailers such as liquor stores. It is also used by premium goods chains.
Breadth and Depth are Balanced
This strategy focuses on the mass audience. Offer the best selection of products for the majority of customers. This means maintaining the main positions in most groups, without focusing on expansion and without overloading the warehouse. To do this, you need to constantly analyze sales data and adjust the assortment in time. In addition, it is quite vague what the optimal product assortment is, and standing out is much harder to do.
Best for: medium-sized supermarkets, FMCG chains.
Adaptation of Width and Depth to Market Trends (dynamic strategy)
Flexible assortment management ensures an optimal balance of width and depth depending on the season, customer behavior, and market trends. This way, you can timely reduce the stock of goods that are no longer in demand. However, implementing this strategy requires constant analysis of sales and market conditions and quick implementation of solutions. Logistics and marketing costs may also increase when promoting new items.
Best for: supermarkets that sell several categories of seasonal and holiday products. It can also be used by specialty retailers that sell goods with variable demand.
Product Depth vs Breadth: How to Find the Right Approach?
When looking for a balance between depth and breadth, you should consider the target audience and its behavior. For example, in the US, most shoppers prefer food and beverages, clothing, and footwear— these are the top 3 product categories. The format and positioning of the outlet, competitors, target market trends, and, of course, financial and logistical capabilities are also important.
Consumer Research
How to determine what products customers need? Analyze receipts to find sales drivers. Also, conduct surveys and analyze behavior in focus groups, which will help you understand customer feedback. Be sure to study and take trends into account to identify potentially popular and outdated products.
Items Rationalization
This is the principle of reducing the number of products that do not add value. You need to identify low-turnover products that do not generate significant revenue but take up space in the warehouse. You can also eliminate duplicate products: for example, if only two of five variants of similar sauces actively sell. For rationalization, apply the method of testing in limited groups or in individual outlets: this will help to avoid wrong decisions.
Implementation of AI and ML Solutions
Finding a balance of product assortment breadth that the store carries vs depth in modern conditions is impossible without high-quality analytics. Automated systems based on artificial intelligence and machine learning are able to study huge amounts of internal and external data, identify patterns and trends. They provide recommendations based on which decisions can be made to adjust the width and depth in different periods to boost sales.
The LEAFIO AI platform contains all the necessary tools for this. In particular, the Demand forecasting and Assortment planning software provide testing of assortment scenarios, creation of several drafts of assortment strategies, and an even assortment balance for each category thanks to predefined rules. As a result, you can:
- make strategic decisions to accurately plan for demand, expand your assortment, or increase your depth with minimal risk of miscalculation or lost profits;
- respond to fluctuations in demand in a timely manner, avoiding shortages of goods or accumulation of warehouse surplus;
- manage the assortment based on current customer preferences. This guarantees a high percentage of repeat purchases;
- have products in stock that are aligned with your business needs: no frozen inventory and huge write-off costs.
Key сonclusions
A wider assortment means a broader customer base but also requires additional costs.
Product depth increases customer loyalty but often leads to sales cannibalization.
To achieve the optimal balance of breadth and depth, study customers, optimize item range, and implement AI-based systems for data analysis and forecasting. These will help you accurately plan demand, manage your assortment, and avoid overstocking.
